Other name(s): BcBOT2; CND15

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphohydrolase (presilphiperfolan-8β-ol-forming)

Comments: Requires Mg2+. Presilphiperfolan-8β-ol is the precursor of botrydial, a phytotoxic sesquiterpene metabolite secreted by the fungus Botryotinia fuckeliana (Botrytis cinerea), the causal agent of gray mold disease in plants.
